Subject: [PATCH] af-packet: dump counters when timeout occurs

When traffic is becoming null (mainly seen in tests) we reach the
situation where there is timeouts in the poll on the socket and
only that. Existing code is then just looping on the poll and
the result is that the packet iface counters are not updated.

This patch calls the dump counter function to be sure to get
the counter right faster (and not only right at exit).
